22. There are large quantities of methane gas (CH4) stored in the permafrost soils (soils that remain frozen throughout the year), located in the high latitudes of the Northern Hemisphere. When permafrost soils thaw (or melt), the stored methane gas is released into the atmosphere.c. If a significant fraction of the permafrost soils thaws, describe the feedback process involving the storage of methane within permafrost soils. Make sure you clearly state whether it is a positive feedback, a negative feedback, or neither with respect to changes in temperature.d. Most climate models do not include this possible feedback. How would including this feedback mechanism act to change the models’ predictions of future climate change?
